LADLE.

SPECIFICATION forming part of Letters Patent No. 453,437, dated June 2, 1891.

Application filed July 2, 1890. Serial No. 357,472. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES COLLIER, a citizen of the United States, residing in May- Wood, in the county of Cook andState of Illinois, have invented a new and useful Improvement in Ladles for Casting Annular Steel Ingots, of which the following is a speci-' fication.

My invention relates to improvements in apparatus for pouring molten steel into annular molds in casting annular ingots for use in the manufacture of rolled-steel tires or rings.

The object of my invention is to provide a simple, durable, and efficient device for deflecting or directing the stream of molten metal into an annular or substantially annular form as it. is poured from the ladle.

My invention consists in a pouring ladle or vessel having a pouring nozzle or opening of an annular or substantially annular form and conforming to the annular mold into which the metal is poured, so that the stream of metal may be deflected or poured into every part of the mold at the same time.

It further consists in the novel devices and novel combinations of parts and devices herein shown and described, and more particularly pointed out in the claims.

In the accompanying drawings, which form a part of this specification, and in which simi-' lar letters of reference indicate like parts, Figure 1 is a side elevation, partly in section, of a device embodying my invention; and Fig. 2 is a bot-tom View of the pouring-nozzle.

In the drawings, A represents a ladle of any suitable or customary form and having the usual orifice in its bottom, and a plug or valve a and loose neck a, slide a guide a and lever (t for operating the plug or valve.

B is an annular mold, and C its core, into which the metal is to be poured to form the annular ingot X.

D is an inverted-funnel-shaped nozzle attached to the ladle A, and D is a deflector or core-piece, preferably of a dome shape, se-

providing the dome-plate D with projecting arms 01, which fit in slots (2 cut in the rim of the nozzle D, so that the keys or pins (1 may be inserted under the projecting arms (1. To properly center the removable dome-plate D with the nozzle D, I provide the nozzle D and dome D with registering shoulders d The nozzle D and dome D may be made of any suitable material known to those skilled in the art. I ordinarily. prefer to make them of steel lined on the inside with refractory material, such as clay or plumbago, one or both. To further protect the dome D at its center, which receives the full force of the stream, I form a recess 01 therein and fill it with refractory material. The annular orifice d of the pouring-nozzle should be concentric With the annular mold during the pourin opera tion, and the dome or core plate D should project at its edges slightly over or beyond the core C of the mold.

As the deflector or dome plate D is at tached to or combined with the pouring-non zle, it, like the nozzle itself, is maintained at a high temperature during the whole pouring operation, so that it does not tend to chill the metal, as would be the case to a greater or less extent if a separate domeplate were placed upon each mold. The do1ne-plate being also combined with or confined in the surrounding inverted-funnel-shaped nozzle, the shell of the nozzle prevents any tendency of the metal to splatter when it first strikes the deflector 0r dome D.

I prefer to employ only two supportingarms (1 for connecting the dome-plate to the bell-shaped shell D of the nozzle, as I find this number to be sufficient. However, any desired number of supporting-arms may be employed.

I claim 1. The combination, with an annular mold, of a pouring ladle or vessel, a pouring-nozzle D, and a deflector-plate D, attached to said nozzle, substantially as specified.

2. The combination, with an annular mold, of a pouring-vessel and an inverted-funnelshaped nozzle D, furnished with a domeshaped deflector D, substantially as specified.

3. A pouring-ladle having an inverted-funnel-shaped pouring-nozzle provided with a pouring-piece or deflector for giving an annular or substantially annular orifice to the nozzle, substantially as specified.

4. The combination, with a pouring-ladle, of an inverted-funnel-shaped nozzle D, having a core or deflector piece D removablysecured thereto, substantially as specified.

5. The combination, with a ladle, of a circular nozzle D, having slots d in its rim, and a round deflector-piece D, furnished with arms cl (1, fitting in said slots, and keys or pins d whereby the metal may be deflected into a substantially annular stream as it is poured, substantially as specified.

6. The combination, with a ladle, of a circular nozzle D, having slot (Z in its rim, and a round deflector or piece D, furnished with arms (1' d, fitting in said slots, and keys or pins d, said nozzle D and deflector D having registering shoulders to center the deflector-piece in the nozzle, whereby the metal may be deflected into a substantially annular stream as it is poured, substantially as speciled.

7. The combination, in a ladle, with an in- Verted-funnel-shaped nozzle D and a domeshaped deflector D, substantially as specified.

8. The combination, in a ladle, with an in-' verted-fnnnel-shaped nozzle D and a domeshaped deflector D, said deflector-piece having a central recess filled with refractory material, substantially as specified.

CHARLES COLLIER.
